Prediction of heavy metals in polluted mangrove soils in Brazil with the highest reported levels of mercury using near-infrared spectroscopy.

Infrared reflectance spectroscopy has demonstrated potential as a tool for monitoring and preventing contamination in different environments. The objective of this study was to evaluate the usage of near-infrared spectroscopy for predicting heavy-metal contamination in mangrove soils from the Botafogo River estuary located in Pernambuco State, Northeastern Brazil. These soils exhibit the highest mercury (Hg) levels ever reported for Brazilian mangrove soils.

[Emergencies-Infinite worlds? : Extended reality as a medium in the education, continuing and advanced training in emergency medicine].

Background: Simulation training is indispensable in emergency medicine, especially for enhancing patient safety. Methods and technologies used include a wide spectrum ranging from simple skill trainers to complex full-scale simulated environments integrating standardized patient actors. Limitations include the simulation of dynamic changes of clinical symptoms, the depiction of emotions and patient movements as well as complex environments, such as lively traffic.

[Learning with digital media in emergency medicine-a path through the jungle of possibilities].

Background: Digital media, such as podcasts, wikis, ePortfolios, and extended reality applications, provide excellent learning opportunities with a high degree of connectivity and flexibility for learners, as well as for learning facilitators. This not only enables location-independent and pandemic-resilient learning, but also a high degree of autonomy for the learners. The megatrend of digitalization opens up many possibilities, but there are also stumbling blocks and limitations.
